Waste minimisation and the quantified self
Last month, Sutton Council was looking for ways to save £925K a year in waste collection costs. There was an online discussion where residents were asked to come up with ideas for making savings and also give their views on suggestions made by the council.
Some of the ideas such as reorganising waste collection shifts to enable the council to halve the number of vehicles are efficiencies that would have a relatively minor impact on residents. Others inevitably are focussing directly on how much of their household waste is being recycled by residents and how much is being sent to landfill.
Rewards for recycling
Rewards for recycling or fines for not recycling enough are among the options. Introducing penalties for bad behaviour isn’t a very popular idea among the public and also in many councils who would rather have constructive rather than punitive relations with their residents. Moreover, there are many practical difficulties in running a punitive scheme. It’s easy enough to put your waste in someone else’s bin unless every bin is fitted with a lock. A trial in Norfolk failed due to numerous technical problems and also led to a 250% increase in fly tipping.
Windsor and Maidenhead are in the process of rolling out a borough-wide recycling rewards scheme after a successful trial with 6500 households.
You can get fantastic rewards at participating businesses like M&S, Legoland, Magnet and Windsor Leisure Centres or you can donate your points to the RecycleBank Green Schools Scheme.
Chip and bin
As with the Norfolk scheme, Windsor and Maidenhead are using so-called chip-and-bin technology. Residents’ recycling bins are fitted with an RFID chip identifying the household to which it belongs. The bin is weighed automatically as it’s emptied into the collection vehicle and the weight is added to the appropriate household’s account. RFID is a short-range radio system that unlike barcodes doesn’t require manual scanning and enables bins to be identified automatically as part of the emptying process.
While we wait to see whether Windsor and Maidenhead’s scheme will have a positive long-term impact on residents’ recycling habits, there’s another approach we could consider. Instead of the council weighing your bin, why not do it yourself?
The quantified self
We’re all familiar with large organisations collecting data about us, whether it’s some part of government, or the supermarket recording our every purchase for their loyalty card scheme. Many people are sceptical about or outright hostile to the increasing amount of intelligence gathering directed at us as citizens and shoppers. Whether well-intended and well-managed or not, this database-building nonetheless chips away another little bit of our privacy.
But technology observers have recently been following the trend for some people to collect this kind of data about themselves. This concept of the quantified self pulls together a diverse set of self-monitoring and self-improvement practices in which people collect data about themselves, analyse it and use it as evidence to support decision making and behaviour changes.
Some quantified self (QS) applications need you to type data into a website. Want to ramp up your drinking? Try DrinkingDiary. Sex life too hot to handle? Bedpost can help you cool it down. Others use common gadgets like smartphones. Runkeeper will track how far and how often you run, where you’ve been and will let you share your progress with others in its own community.
Some QS apps are sophisticated product service systems that come with their own custom hardware that takes the pain out of data collection. Fitbit gives you a tiny clip-on device that works as a pedometer to track your exercise levels while you’re awake and monitors your sleep time and quality while you’re in bed.
The Withings Body Scale is no ordinary bathroom scale. It doesn’t just let you weigh yourself, it wirelessly and automatically transmits your weight to a central database, from where you can monitor your progress on the web and through various mobile apps.
So if we can weigh our bodies, why not our bins?
DIY chip and bin — the pilot project
My own “pilot project” for tracking my waste disposal has so far taken around ten minutes of my time and cost £3.50 in hard cash. The money went on a portable luggage scale that I picked up in my local newsagent and the time went building a simple Google Spreadsheet and form that lets me easily type in the weight of each bin bag before I put it out into the bins. Here in Sutton we’ve got a brown bin for landfill waste and a green bin for recycling. I’m weighing both. When I fill in the Google form the numbers get automatically added to the spreadsheet along with the current date. Then I can just total up the columns and see how much I’m landfilling and recycling over time. It’s a good start.
Despite its low cost and relative simplicity, my system requires a fair bit of effort to get started and to diligently weigh and record each bag as it goes out to the bins. But what if we could buy kitchen bins that did the weighing and recording for us like the Withings Body Scale? I’m sure it’s only a matter of time before we can. Technologically it’s almost the same product, though the software would need adapting to the different context of having two or more bins recording weights of different waste products rather than a single scale recording many people’s weights. This isn’t rocket science.
But will you behave better?
What’s likely to be much harder than collecting this data is using it to help people actually change their behaviour. Someone who goes to buy or contrive a weighing bin is at least starting off with some motivation and a good intention. Sustaining that might be hard. As with many fitness apps, a social networking component where the user could share and compare their data with others in similar households might provide sufficient motivation and social reinforcement to keep going. A web-based system could send occasional suggestions for ways to waste less and recycle more, even in the form of advertisements for eco-friendly packaged products like those in Amazon’s 100% recyclable Frustration-Free Packaging.
Twenty minutes into the future…
Now imagine what could be done if this system had access (with your permission, of course) to your supermarket loyalty card data. Suggestions on how to substitute poorly-packaged products for comparable ones based on your actual shopping habits? Suggestions on how you could buy larger packs of existing products that would have proportionally less packaging? Having access to this info on your smartphone while you’re in the shop? Discount vouchers as a little extra nudge to get you started? It’s all perfectly feasible.
If people can do data for themselves, do councils still have a role to play? One way might be to sidestep the whole issue of people getting their own weighing bins and providing bin weight data collected through chip-and-bin straight to residents without operating a local penalty or reward scheme. Residents could then participate in any third-party reward scheme that they chose, most likely operated by a supermarket or another retailer. People would appreciate the choice and flexibility of being in control of how their data was used and could pick a reward scheme that suited them best. Retailers would have greater incentive to work with their suppliers to improve packaging. Councils would benefit from lower landfill taxes and greater recycling rates without going to the trouble of running their own reward schemes or getting out the thumbscrews.
Whose data? Our data!
The biggest barrier to making this happen isn’t the technology. We’ve already got that. The problem is getting the organisations that collect data about us to give us access. We need a new deal with the organisations that know more about us than we know ourselves: If you want my data I get to use it too and I get a secure way of sharing it with trusted third parties that can do something good with it that benefits me. If you want to log my phone calls or my purchases or the weight of my bin every time you collect it — show me your API. Quid pro quo or GTFO.
We’re starting to make good progress with the open data movement to get government to release its non-personal data for everyone to use. The next step is to get equal access to the personal data that government and business holds about us so it can work for us as well as it works for them. Then we can have an information society in which everyone benefits rather than an information technology society that just reinforces the status quo. It might start with our bins but it won’t end there.
